T0 all whom 'it may concern Be it known that I, Cr-iannns F. Sinonisr, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Tater-Measuring Devices, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The type of measuring device, to which the present improvements more especially relate, is that wherein an oscillatory bucket is employed, having two similar compartments, one on each side of the axis of oscillation, said bucket being provided with discharge valves in the compartments, respectively, adapted to be opened upon depression of the corresponding end of the bucket. A weight, movable on the bucket transversely of its axis, assists in maintaining the one compartment in depressed position until. a predetermined weight of water, or other article being measured, flows into the other, raised compartment.

The object o fthe invention is to provide a measuring device of this kind wherein a high degree of accuracy is attained by a proper diversion of the inflowing material from one bucket to the other, and by shutting off the supply during the tilting movement of the bucket.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of the various mechanical forms in which the principle of the invention may be used.

In said annexed drawing: Figure l is a longitudinal cross-section of my improved measuring device; Fig. 2 is a transverse cross-section of the same; and Fig. 3 is an elevation of a detail.

The oscillatory bucket l, which constitutes the principal operative feature of the device, is preferably entirely inclosed in a casing 2 having a removable cover 3 in order to permit assembly of the parts, and a removable plate L on one side, through which access may be gained into the interior of the casing for the purpose of adjustment and examination of the bucket and other operative parts. The supply of water, or other material to be measured, is through a short pipe 5 secured in an' opening 6 in the cover of the casing and adapted for exterior connection with a suitable suply line (not shown). Similarly a connection a is provided in the bottom of the casing for the escape of the liquid discharged from the bucket. rlChe latter is of general rectangular form and is divided by a central transverse partition 8 into two similar compartments. rEhe end walls of the bucket flare outwardly from the bottom, whereby there is a displacement of the contents of a compartment toward the corresponding end of the bucket, when such end is depressed. The upper edges of the walls of the bucket moreover slope, as clearly shown in Fig. 1, so that those forming the sides of the respective compartments lie substantially horizontal when a particular compartment is in its lower'position. In the bottom of the bucket, near the end of each compartment, is provided one or more valves 9, (two being shown in the structure illustrated), so arranged as to normally seat in the raised position of the corresponding bucket end, as shown at the left in Fig. l; the stems 10, however, of such valves project through the bottom in position to engage bosses l1 rising from the bottom of the casing, whereby the valves are lifted, as shown at the right in Fig. l, and the corresponding compartment thus allowed to drain, when the end in question is depressed.

The supply pipe 5 in the cover of the casing is substantially centrally disposed with respect to the bucket 1, so as to lie directly over the partition 8, which separates the latter into two compartments. While such partition will lie first on one side and then on the other of the line of discharge of the supply pipe, in order to insure the proper diversion of such supply to the raised compartment of the bucket, a movable, preferably oscillatory, nozzle 12 is provided, such nozzle being operatively connected with the bucket by means of a link 18, which is pivoted at one end to the latter, and has a lost-motion connection at the other with the nozzle consisting of two spaced stops 14E.

In addition to the foregoing, I provide in the end of the supply pipe 5 a valve 15, preferably of the butterfly type shown, which is normally open, as shown in Fig. 1, when either end of the bucket is depressed. The stem 16 of such valve, however, is connected with one end of the bucket by means of a link 17 and a lever 18, so arranged that when the bucket is balanced and lies in substantially horizontal position, said valve will close the supply pipe. By reason of the lost-motion connection for operating the nozzle, the latter is undisturbed until the bucket reaches such horizontal position and starts to tilt in the opposite direction from that which it previously occupied. The valve is formed with a by-pass 19 of restricted cross-section, so that a limited quantity of water will continue to be supplied, even after the valve is closed and thus the overbalancing of the bucket will be insured. At the same time a very nice and exact measurement of the quantity of water supplied to a compartment before the bucket swings over is obtained, there being no chance of a large excess of water being supplied to such a compartment while the bucket is tilting. Before the valve 15 is opened again, the link will have swung the nozzle across the partition, so that the regular supply may again be resumed in filling the previously emptied compartment. The counter-balancing ball 20 is adapted to roll along a V-shaped way 21, secured to one side of the bucket, as best shown in Fig. 2, and in order to take upthe shock of such balls movement as it reaches each end of its path, a resilient buffer 22 is mounted in the end wall of the casing in position to receive the impact of the ball, thus eliminating noise and reducing wear.

A suitable register 23 is provided for registering the `oscillations of the bucket, such register being desirably of the one-way operable type and reading in pounds. A register suitable for use in this connection is shown in U. S. Letters Patent No. 1,056,460, issued to me March 18, 1913. The connection between the register and the bucket is effected by means of two segmental gea-rs 24E and 25, one carried on the operating spindle of the register, and the other on a prolongation of the stem 16 of the valve which controls the supply pipe. Such stem being also directly connected with the bucket, it will be seen that not only will the register be actuated each time the bucket tilts, but that it will be impossible for any one to operate the register from without, because of the direct gear connection which it thus has with the bucket itself.

l have found by actual tests that unusually accurate results in weighing water can be obtained with the foregoing apparatus. At the same time it is extremely simple and the parts so constructed as to present little likelihood of getting out of order. A very considerable field for the use of a device of this kind, it should be explained in conclusion is found in measuring water of condensation both in steam power plants and steam radiating installations. In the latter, especially, it is quite common to measure the amount of heat supplied by the weight of water of condensation, and it is hence essential to determine the latter accurately, volume alone being insufficient to afford a correct basis, since the latter obviously varies with the temperature at which the measurement is made.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

l therefore particularly point out and distinctly claim as my invention 1.
